Product Details

TotalBoat Penetrating Epoxy is a low-viscosity wood rot restoration and repair solution that seals deeper & cures stronger than industry-leading penetrating epoxies. It has no VOCs, no odor & is 100% waterproof once cured.

This 2:1 system is ideal for restoring rotten or damaged wood, or sealing new wood for lasting protection against humidity, salt, mold & mildew. It works by gluing cellulose (wood) fibers back together, sealing a bare, porous wood surface from the inside out. Double the penetrating power by mixing acetone with the epoxy resin solution in equal volume. Easy to apply by brush, roller, or inject via syringe. Surfaces may be painted or varnished after light sanding.

Choose from Traditional (65-90 F) or Cold Weather (40-65 F) formulas in Pint, Quart, 1/2 Gallon & Gallon kits.

Info & Guides

NO VOCS, NO SMELL.

Cleanup is easy. Wear latex gloves, wash off with soap and water. No solvents required.


APPLICATION NOTE: The wood must be bare and unfinished. Also, TotalBoat Penetrating Epoxy will not penetrate and level well when applied over some stains. Always test an area first. DO NOT USE on top of Minwax oil-based stains.


TotalBoat Cold Weather Penetrating Epoxy is perfect for use during the colder seasons. Compared to our traditional TotalBoat Penetrating Epoxy, our Cold Weather formula offers similar performance characteristics, but cures completely and reliably in cooler temperatures. Its tack-free properties also allow you to sand sooner.

WARNING: TotalBoat Cold Weather Penetrating Epoxy should not be used as a fast-cure epoxy in warmer temperature conditions because doing so can be unsafe and result in premature exotherm, brittleness, and improper curing.

Application Temperature Ranges:

  • Traditional formula - 65-90°F
  • Cold Weather formula - 40-65°F

Excellent Product
By Mark from Houston Texas

Verified Purchase

I used this to seal a white oak sailboat rudder that I made. The epoxy soaked into the raw wood beautifully and the high gloss finish was achieved after only two coats.

Bottom Line Yes, I would recommend to a friend

old boat restoration
By Mike the boatman from Lake Arrowhead, ca.

Verified Purchase

I am restoring a 1954 Glen L. Witt outboard runabout. All wood construction. The deck is plywood and I took it down to bare wood. Then I used penetrating epoxy (thinned 50/50 with acetone) to firm up and prepare for varnish. The thinned epoxy penetrated deep into the plywood and the whole structure feels much stronger. I have now put on two coats of varnish (at least one more to come) and it looks fabulous.

Bottom Line Yes, I would recommend to a friend

Excellent for sealing new wood
By Old Dog from Cleveland, OH

I made a teak and holly plywood floor for our powerboat after removing the old carpet 4 years ago. I sealed the wood after final cut according to the instructions, it has been spectacular. Standing water after a waterline break, spills, etc, the floor looks perfect. No discoloration, no staining. The 100% penetration of this product worked perfectly.

Bottom Line Yes, I would recommend to a friend

Not as penetrating as I thought
By Women woodworker from Vancouver Washington

Verified Purchase

It worked ok. I Don't think that the acetone made it penetrate any better. I wish that the instructions were clearer it never mentioned that u should sand it first. Sort of confused of the difference between this and the table top epoxy.
